Looks rather good.
However I do have one suggestion, one to help us "filter" possible colonies. Now that LG worlds are a thing, the list of possible planets to colonize is very long. So I would have one suggestion. Since most of those planets have extremely low population capacity, it would be nice to have a filter to only show possible colonies with population cap above a certain limit.
I don't know, 25 millions? 10 millions? Because when I see a planet with a max population capacity of 0.05, I'm not really interested in colonizing that. Except in extremely rare cases.
Something that would probably help a LOT would be to allow sorting on the columns. I would recommend the way Rule the Waves (and many others) do it - If you sort on column A, then column B, then column C, ties in C are resolved by keeping the previous "B" order; if "B" is also tied then they're resolved by the "A" order etc. This would allow you to e.g. allow you to sort on atmosphere type (Venusian vs oxy-nitro) with a sub-sort of population capacity. Note that this is helped a lot if the columns are arranged so that many of them have discrete values (e.g. Venusian vs oxy-nitro) as opposed to continuous "double" values. So for this to work well, the "(0.1)" in the atmosphere column should maybe be in a separate column, so that all oxy-nitros are tied.
Another game to play here would be to allow filtering of the list - select a bunch of rows and then push a button and everything else goes into a "hidden" state. That would let you hone in on optimal ranges on several "double" columns, e.g. first hide all low population cap bodies, then hide high pressure, then ....
